Many China-based sellers who were kicked off Amazon for rule violations have turned to Walmart's online marketplace to reach US consumers
Ever since Amazon.com Inc. began kicking tens of thousands of Chinese merchants off its platform last April for faking customer reviews …
Context & Ripple Effects
Amazon's review-fraud purge escalated from closing 3,000 seller accounts tied to about 600 Chinese brands in September 2021 to removing tens of thousands of China-based merchants from April onward, and the sellers did not leave US e-commerce — they relocated. Walmart's marketplace is the landing spot, arriving on top of a platform that had already scaled from six third-party sellers in 2014 to roughly 70,000 by 2020, when Reuters reported some observers worrying its systems were stressed.
The migration matters because it tests whether marketplace enforcement actually changes seller behavior or merely redistributes it: the same generic-goods sellers Amazon has fought for gaming its algorithm now face a Walmart vetting apparatus built for a much smaller seller base.
First-order effects
- Tens of thousands of China-based sellers banned from Amazon since April regain immediate access to US consumers through Walmart's marketplace, converting Amazon's enforcement action into Walmart's seller growth.
- Walmart inherits the review-manipulation and rule-evasion risk Amazon spent 2021 purging, straining the marketplace infrastructure Reuters already flagged as stressed at ~70,000 sellers.
Second-order effects
- Amazon's crackdown loses pricing power if banned sellers can rebuild volume on a rival platform, pressuring Walmart to either tighten vetting — raising its own onboarding costs — or accept the enforcement arbitrage.
- Competition between Amazon and Walmart shifts toward seller-vetting standards as a differentiator, since the same merchants now operate on both platforms.
Third-order effects
- If bans on one marketplace keep routing sellers to the next, platform enforcement alone cannot clean up third-party e-commerce, pointing toward shared seller-identity standards or regulatory involvement in cross-marketplace accountability.
The trend: Marketplace enforcement is becoming redistribution rather than removal, as banned sellers migrate between Amazon and Walmart faster than either platform's vetting can absorb them.
